The Role

As a Product Designer at Moises, you’ll shape how more than 70 million musicians experience AI. You’ll design products that help people learn, practice, and create—from the very first interaction to the nuanced workflows they rely on every day. Your work will span Mobile, Web, Desktop, and Plugins, where every design decision contributes to a connected, cohesive product ecosystem.This role is about making powerful technology feel effortless. You’ll transform complex AI capabilities into intuitive experiences through strong product thinking, systems thinking, and exceptional craft. Working closely with Product, Engineering, AI, and Data, you’ll help define problems, explore solutions, validate ideas, and deliver products that musicians love.We’re looking for designers who combine curiosity with ownership. At Moises, velocity is the culture—not the exception. We work in small, highly collaborative teams with low ceremony and a bias toward action. You’ll be trusted to navigate ambiguity, make thoughtful tradeoffs, and move quickly, always balancing simplicity, scalability, and user value.

What You Will Work On

Own end-to-end design for major product areas, including discovery flows, core interaction patterns, and final visual execution that can span from iOS, Android, and web.
Translate complex audio AI capabilities into interfaces that feel immediate and intuitive, without exposing the complexity underneath.
Run and synthesize user research with musicians across skill levels and use cases, turning what you learn into decisions the team can act on.
Contribute to and evolve the design system, keeping it coherent and scalable across platforms.
Partner with PMs and engineers from early problem framing through to shipped feature, helping define what the problem is before designing a solution.
Give and receive direct, specific design critique that raises the quality bar for everyone working on the product.

Required

5+ years designing complex software that real people use daily, with a portfolio showing powerful technology made to feel simple
Fluency moving between fidelities fast, from napkin sketch to coded prototype in a day, because the fastest way to settle a debate is to make the thing real
Comfort in ambiguity and zero-to-one work: you have shipped before the problem was well-defined, without a design system, a clear spec, or a playbook to copy
Track record of defining interaction paradigms, not just executing within them, including patterns you invented rather than iterated on
Strong written communication: you can explain the reasoning behind a design decision as clearly as you can show it in Figma
Proven ability to do your own research and bring it back as product direction, not just design artifacts. You talk to customers, watch how they work, and walk out knowing what to build next
Prototypes in code as a default, not a last resort. Cursor, Claude Code, or similar tools are already part of how you work

Nice to Have

Experience designing AI-native products and the unique UX challenges of probabilistic systems.
Experience with music production, audio engineering, or playing an instrument.
Familiarity with DAWs, VST plugins, or other professional music software.
Experience designing cohesive experiences across multiple platforms and devices.
Motion design, interaction animation, or advanced prototyping skills.

What It Is Like to Work Here

The team is distributed across Brazil, the United States, and Europe, with offices in João Pessoa, Salt Lake City, and São Paulo. Designers work remotely and in hybrid arrangements depending on location. Coordination happens across time zones, so written communication and async judgment matter more here than they do at most companies.

You will have real ownership. There is no design layer that exists purely to execute someone else's vision. You will frame problems, push back on scope, make calls on interaction patterns, and defend those calls in critique. The VP of Product is your direct line, and the expectation is that you bring a point of view, not just deliverables.

Moises is built for musicians, and that shapes how design decisions get made. Whether or not you play an instrument, you will spend time with musicians across skill levels, watching how they actually use the product and what gets in their way. That context is not optional background knowledge. It is how good design decisions get made here.

You will be working alongside a small product design team where Diego Araujo and others are already thinking hard about consistency, systems, and how AI surfaces should behave. You will contribute to that work directly, not inherit it from a distance.

The Details

This is a full-time remote role. Candidates based in Brazil or the United States are preferred given where the rest of the team is concentrated.
